Owing to conflicting market exclusivity rights, the U.S. Food and Drug Administration (FDA) has partially rescinded its decision to approve BeneFIX and Ixinity for additional indications both therapies received last year for the treatment of hemophilia B, according to the National Hemophilia Foundation. Pfizer’s BeneFIX and…

The U.S. Food and Drug Administration (FDA) has granted fast track designation to efanesoctocog alfa, an investigational factor VIII (FVIII) replacement therapy for treating hemophilia A, Sanofi, one of the therapy’s developers, announced in a press release. This designation is given to accelerate the development and review of…

When given as a prophylactic, or preventive therapy, Advate worked better than on-demand treatment at lowering the number of spontaneous bleeds in people with moderate or severe hemophilia A, according to seven-year data from a real-world study. A separate analysis of the study, called AHEAD International (NCT02078427),…

A single dose of the experimental gene therapy SPK-8016 showed promising safety and efficacy in lowering the frequency of bleeds and the need for infusions in men with severe hemophilia A. These preliminary findings from an ongoing Phase 1/2 trial (NCT03734588) were presented by Spencer Sullivan, MD,…

When given as a preventive treatment for nearly six years, Hemlibra (emicizumab) safely and effectively lowered the number of bleeding episodes in patients with severe hemophilia A, according to data from a Phase 1 clinical trial and its long-term extension study. Importantly, reductions in the number of bleeds…

A single dose of the experimental gene therapy FLT180a can safely maintain the activity levels of factor IX (FIX) within a normal range for nearly three years, effectively preventing bleeds and the need for replacement therapies in patients with hemophilia B, according to updated data from a Phase 1/2…

Women with genetic blood disorders, including those who are carriers of hemophilia A and B, face multiple uncertainties surrounding their diagnosis, according to a recent interview-based study. Many women claimed to have been misdiagnosed initially and did not receive a correct diagnosis until after the disease had…

Note: This story was updated Nov. 6, 2020, to clarify key scientific concepts. The gene-editing tool CRISPR/Cas9 enables a targeted gene insertion approach that may be superior to conventional gene therapy at restoring the activity of factor IX (FIX), the blood-clotting protein missing in people with…

Reports of translucent particles of being detected in Hemlibra (emicizumab) in 2019 do not pose a safety risk or affect the therapy’s effectiveness and, according to Roche, health authorities have agreed that the treatment’s benefit/risk profile remains unchanged. Yet, the company is proposing the use of a…
